I've got speed "humps" in my neighborhood. If I try to drive over the center they'll scrape. No big deal though, because they aren't structural and certainly aren't designed to be. These will definitely snap back if you hit anything of substance.
You won't scrape on speed bumps since the whole car is being lifted up. These will only scrape or hit things you drive over that are between your tires.
